SPECIFICATION formingpart of Letters Patent No. 234,056, dated November2, 1880. Application filed October 8, 1879.

To all whom it may concern:

Be it known that I, WILBUR F. OSBORNE, of Ansonia, in the county of NewHaven and State of Connecticut, have invented certain new and usefulImprovements in the Method of Weaving Suspender Strap Webbing, of whichthe following is a specification.

This invention relates to certain improvements in the method of weavingsuspenderstrap webbing having woven button-holes; and it has for itsobject to form a Jacquard figure upon the body of the strap, utilizingfor this purpose that shuttle employed for forming the selvage at oneedge of the button-hole that usually remains idle during the weaving ofthe main body of the strap.

To this end my invention comprises the method of weaving with twoshuttles suspender-strap webbing having woven button-holes, whichconsistsin weaving the body of the strap and the portion on one side ofthe button-hole with the weft of one shuttle, and in weaving a Jacquardfigure on the body of the strap and that portion of said strap on theother side of the button-hole with the weft of the other shuttle,essentially as hereinafter described.

In the accompanying drawings, Figure 1 is a view of a suspenderbutton-hole strap woven according to my improved method. Fig. 2 is anenlarged view of a sufficient portion of a button-hole strap toillustrate my invention, the threads being separated in order to showtheir respective courses. Figs. 3, 4, and 5 are viewsillustratin g therequired shedding of the warp in weaving a button-hole strap by myimproved method.

Referring to Fig.1 of the drawings, the weft of a single shuttle formsthe entire portion B of the strap, the warp being shedded as shown inFig. 3, alternate threads at and b being respectively raised andlowered, and when the point 0 is reached one half of the warp, a, fromthe center to the edge, is raised and the other half, b, depressedsufficiently to permit the two halves to be shedded, as shown in Fig. 5,to allow separate shuttles to be used in weaving in the weft of the twohalves, forming inner selvages for each half for a proper distance toform the inner edges of the button-hole, the shuttle carrying theregular weft forming one side and that carrying the additional weft theother. When the pointd is reached the edges of the button-hole have beencompleted. The two halves of the warp are then brought in the same planeand shedded in three divisions, as shown in Fig. 4, when one of theshuttles is thrown clear across above the warp-threads b and below thewarp-thread e, weaving in the regular weft for the entire width of thestrap for the whole length of the body E of the strap between thebutton-holes, while the other shuttle, carrying the additional weft, isthrown across above the thread eand below thethreads a, the thread 6bringing into sight the additional weft, so that by a proper arrangementof the number and positions of the threads 0 of the middle division ofthe warp, which will be governed by the Jacquard, this additional weftis utilized for forming the Jacquard figure f until the point 61 at theopposite end of the strap is reached, when the two halves of the warpare again separated and shedded. as in Fig. 5, and the separate shuttlesweave their respective portions of the strap at the sides of thebutton-hole until the point e is reached, when one of the shuttles isthrown out of operation and the other continues, forming the full widthof the weft of the strap.

In Fig. 2 the weft-thread g is the regular weft, and It designates theadditional weft. Fig. 4 shows the shed of the warp at the line 'iof Fig.2 in the process of weaving where but one warp-thread is used to bringthe additional weftthread into sight. The two weftthreads should bepreferably of different colors, in order that the figure may be of adifferent color from the body of the strap; or the additionalweft-thread may be of a different material from the other, and the copin the additional shuttle may be changed after weaving the firstbutton-hole portion and a thread of a different kind used for weaving inthe figure .until the next button-hole is reached, when the cop used atthe first may be replaced.

I am aware that in weaving button-hole straps with two shuttles theadditional weftthread has been woven into the body of the strap for thepurpose of hiding what is called the floating filling,. and I do notclaim such method of weaving.

What I claim is- The method herein described of weaving suspenderbutton-hole straps with two shuttles, the same consisting in weaving thebody 5 of the strap with the weft of one shuttle and at the same timeweaving a Jacquard figure thereon with the weft of the other shuttle,and weaving one side of the button-hole portion of the strap with one ofsaid shuttles and the 1 other side with the other shuttle, substantiallyto as set forth.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence 0 the subscribing witnesses.

WILBUR F. OSBORNE.
